Hey there :)

We know the formula for simple interest is 
I = prt
{ The picture includes what each stands for }

Lehena:
Initial amount = $100
Interest rate = 2.5% = \frac{2.5}{100} = 0.025
Time = 3 years
I = ( 100 )( 0.025 )( 3 )
  = 7.5$

Total = $100 + $7.5 = $107.5

Marty:
Initial amount = $100
Interest rate = 2% = \frac{2}{100} = 0.02
Time = 3 years
I = ( 100 )( 0.02 )( 3 ) 
  = $6

Total = $100 + $6 = $106

How much more than Marty did Lehena receive?
= Total Amount of Lehena - Total Amount of Marty
= 107.5 - 106
= $1.5

Your answer will be option B) $1.50

Y (x)=400 (1.005)^4x
Where x is the number of years

Part B
The value of the account after 5 years

Help!! Picture below
deff fn [24]

Answer:

Option A. (a/2,0)

Step-by-step explanation:

we know that

If triangle ABC is a right isosceles triangle

then

AB=AC

m<ABC=m<ACB=45°

therefore

The coordinate of point C is (a,0)

the x-coordinate of the midpoint M is equal to

(0+a)/2=a/2

The coordinates of point M are (a/2,0)

A clown bought 5 bags of round balloons with 24 balloons in each bag. The clown also bought 3 bags of long balloons with 36 ball
dimaraw [331]

Answer:

247 blown up balloon left

Step-by-step explanation:

5 bags of round balloon with 24 balloon in each bag =

                                  = 5 x 24 = 120 round balloons

3 bags of long balloon with 36 balloon in each bag =

                                   = 3 x 36 = 108 long balloons

Part 1 Answer

120 round balloons -  108 long balloon = 12 balloons

therefore the clown bought 12 more round balloon than long balloon

 

Part 2

3 bags of heart-shaped balloons with 14 balloons in each bag =

                                    = 3 x 14= 42 heart-shaped balloons

All the balloons were blown which equals

120 round balloons + 108 long balloons + 42 heart-shaped balloons =

                                      = 270 balloons

23 balloons out of the 270 balloons burst which equals

 270 blown balloon - 23 burst balloon = 247 blown-up balloons left

so,

247 blown-up balloons were left
